If the display device or AV amplifier does not support HDCP, only audio
without content protection is output; audio is not output when signal with
content protection is input. Some HDMI/DVI devices check if the
connected device is HDCP compliant and determines whether to output
HDCP signal or not. Since the DFS is HDCP compliant, audio may not be
output if the DFS is connected to a sink device or AV amplifier that does
not support HDCP. In this case, disable HDCP input from the input device
in “
LCD monitors may not output compressed audio, such as Dolby Digital,
DTS, and so on. If playing contents with compressed audio (such as
Blu-ray disc), check the audio output setting. Audio signal that is output
from the source device can be controlled by setting EDID.
Set “

device does not support HDMI signal, the DFS outputs DVI signal
automatically. Check which signal type is supported by the sink device.
Is DVI signal output from the source device? You can check the
input signal type in

DVI signal
may be output depending on EDID settings.
If a source device that does not support 4K is connected to the input
connector to which 4K EDID is set, DVI signal may be output. Change the
